At a Glance
- Calvert-Lewin watches a first-half header come back off the post.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second period.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half effort against the post for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, Cunha restored parity three minutes after the opener when he ran on to a pass from introduced the Dutchman and slid a shot underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The task is not done yet but step by step, Leeds are getting closer to achieving their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their FA Cup journey with a home tie.
